Product Detail

Selank API is a well-defined synthetic neuropeptide composed of seven amino acids (Thr-Lys-Pro-Arg-Pro-Gly-Pro). It is a functional analog of the endogenous immunomodulatory peptide tuftsin and was originally developed within Russian research institutions for studies in neuroscience and neuroimmunology. Due to its ability to cross the blood–brain barrier, Selank has attracted sustained interest in research related to emotional regulation, stress response, and cognitive function.

The API is typically supplied as a high-purity, lyophilized white or off-white powder with a molecular weight of approximately 751.9 Da. It is manufactured under strict quality control procedures and analyzed using HPLC and mass spectrometry to confirm identity and purity, which is generally ≥99%. Each batch is accompanied by a Certificate of Analysis (COA) to ensure structural accuracy, consistency, and reliability for laboratory use. The product is commonly available in milligram-scale quantities suitable for research, analytical validation, and formulation development.

From a research perspective, Selank is primarily studied for its modulatory effects on the GABAergic system and its association with anxiety-related behavioral models, emotional stability, and learning and memory processes. Additional investigations suggest potential involvement in immune signaling and stress-related neurochemical pathways, positioning Selank as a valuable compound in the intersection of neurological and immunological research. Compared with traditional small-molecule anxiolytics, Selank is noted in experimental settings for its lack of pronounced sedative, muscle-relaxant, or cognitive-impairing effects.

Selank API is not approved as a pharmaceutical drug or dietary supplement in most regions and is strictly intended for research and laboratory use only. It is not intended for human or clinical applications. For optimal stability, the lyophilized product should be stored under dry, light-protected, low-temperature conditions. Once reconstituted, appropriate handling and limited storage duration are recommended to maintain peptide integrity.
